CORPORATION OF ILLINOIS Y Y SIGNAL LANTERN Application filed July 16, 1926, Serial No. 122i854. "'Renewed'February 13, 1929. V

The invention relates to signal lanternssuch as are employed in the railway service by train and yard men, of the general type of the lantern shown in the patent to Hamm & Schuetz, No. 1,415,633, of May 9, 1922.

The object of the present invention is to provide improved means for admitting air to the burner and for holding the globe and staying the upper portion of the font.

The invention consists in a structure such as is hereinafter described, and is illustrated in the accompanying drawings in which Fig. 1 is a detail side elevation of the lantern, some portions being broken away and some portions being shown in section;

Fig. 2 is a detail sectional view on the line 2-2 of Fig. 1; and y Fig. 3 is a detail section on the line 3-3 of Fig. 2. V

The lantern comprises the usual guard frame 10, which may be of wire, the base ring 11' within which the font 12 is seated, the globe 13, the dome 14, and globe holder .15.

Certain details as of the dome 14,-globe holder 15- and the carrying bail being omitted as not beinginvolved in the present invention.

The font 12 may be of any desiredform of construction, being shown as having a body drawn from a sheet of tin and a top plate 16 which may be crimped over the top margin of the body portion and permanently secured thereto as by the use of solder.

The base ring may be of the usual form of construction, its upper portion 17 being of greater diameter than its lower portion, within which the font is seated, thereby providing a passage 18 for air entering the induction ports 19, for supporting combustion. The globe seat is of sheet metal and comprises an upstanding section 20 for enclosing the lower end of the, globe, this section being the upper margin of the base ring to which it may be permanently secured as by clinching. Below the section 20, theholder is flanged inwardlyas shown at 21 to provide a seat for the lower margin of the globe l8. vAnann'ular skirt 22 depends from the inner margin of section 21 of the globe seat andis preferably formed integrally therewith. This for the. imain air supply.

skirt is of.slightly greaterdiameter than the font 12" and extends below- 1 the 7 top: thereof, space being "provided" between the skirt and the font for thepassage of airfrom the chamber 18. Instanding lugs I. 23, .conveniently -u '"formed bylind'enting the skirt'22, engage. the

side wall of the font and prevent; its vibration. The :lowerportionwof the skirt. 22is "fiaredaoutwardlys as shown at:;24 forming a funnel: shape flange: for directing air into the go passage between :the -:.skirt and r: the E-font.

Eor' convenience of description the: air. supplied through theipassages betwe'enzthe skirt 22- and font 12 will rbe termedl the auxiliary HJ'IF'SHPPlyfJfOIHthG combustion chamber. The "length of the skirt isr-immaterial providing 'it extends below: the top ofzthe. fontzandter- -minatewabove air portszasxl9. lThe skirt'22 :Jis provided withi an' annular series of; ports 25 'in its upper-portion; and abovethe top of m thefont' and constituting what; for convenv ience ofadescription, will' bet-termed. the ports Air entering the induction: ports, 19 is admitted into; the body of the lantern: thruthe 'm 'passagezbetweenthezskirt 22 and the font and thru the *portsi25. :Thef two' sets. of currents entering the body interminglei'and.,,are directed towar'dthe burner which, .185 usual, .is

' located -"at' the center of the top of th-eifont. e0

WVhen' the lantern is used in a high windythe interference of'these t-wo currents will :pre 'vent the blowing out-oftheflame.

Ifclaim as my invention: 7 1. In a signal lantern, a base ring having air induction portsaa font'housedrwithin the ibaseringsand' carrying a burner, a -globe .seat at the upper end'ofthe basering-and r,havingi'aidepending annular ported skirt,.

such skirt being" of,'greater diameterfthanthefontand extending below the top thereof and foriming with the side of thefont a passage for air. r

2. In a signal lantern, in combination, 21 ported base ring, a font, inclosed within the ring and spaced therefrom to enclose an air chamber, and a ported wall, crossing the upper end of such chamber and extending downward adjacent tobut spaced from theiauoo side wall of the font and providing with the font wall a restricted air passage.

3. In a signal lantern, in combination, a ported base ring, a font inclosed within the ring and spaced therefrom to inclose an air chamber, and a ported wall, crossing the upper end of such chamber and extending downward adjacent to but spaced from the side wall of the font and having a flaring flange at its lower end, and providing with the font wall a restricted air passage.

4. In a signal lantern, in combination, a font, a ported base ring inclosing, and extending above the font and spaced apart therefrom to form an air chamber, a closure for the air chamber comprising a vertical wall ported above the font and providing with the side wall of the font a restricted upwardly opening air passage.

5. A signal lamp having a combustion chamber provided with a burner, and an air chamber, the air chamber having a main connection with the combustion chamber to sup ply air to the burner, and also provided with an auxiliary air connection with the combustion chamber disposed to discharge air across and diffuse the air supplied by the first mentioned connection.

6. A signal lantern comprising a combustion chamber and an air chamber, a burner in said combustion chamber, the air chamber having induction ports, a closure separating the two chambers and providing air ports in intersecting planes for thepassage of currents of air flowing laterally inwardly and other currents flowing upwardly and intersecting the first named currents within the combustion chamber for diffusing the air as it enters the last named chamber, the intersection of said currents being adjacent to the wall of the combustion chamber and spaced a material distance from said burner.

7. A signal lantern comprising a combustion chamber and an air chamber, the combustion chamber having a burner therein but being otherwise unobstructed, the air chamber having induction ports, a main air passage for conducting air from said air chamber and discharging the same laterally into the combustion chamber and an auxiliary air passage for discharging air upwardly into said combustion chamber, and intersecting the air passing through the auxiliary air passage within said combustion chamber at points adjacent to the wall thereof and spaced from said burner.

In testimony whereof I aflix my signature.
